One of the reasons the internet might have latched on to Trump's runny nose isn't just because the sound was grating. It may have been because of the way Trump has previously pointed out minor ailments such as a sniffle or a cough as an indication that a presidential candidate might not be fit to serve.
The truth is, everyone gets the sniffles sometimes. Even billionaires. Even presidential candidates. It just happened to be Trump's turn while he was being broadcast on live TV and that lead to him becoming Monday's snot-nosed meme-du-jour. But don't be too disappointed, Mr. Trump. Doing something weird on TV and becoming a meme is a rite of passage. It happens to all the best Americans. Just ask Michael Phelps.
